Apple CarPlay to support 3rd party mapping
Apple's Worldwide Developer Conference is currently underway and I noticed they have announced that iOS 12 will support 3rd party navigation apps in CarPlay. No details on exactly how this will work (whether developers will have to change their apps).

Here's a story but at the moment it only mentions Google Maps and Waze. There should be more info soon:

My new VW has CarPlay, I tried it once and haven't used it since. You are forced to use Apple Maps and I was not very impressed. You also have to enable Siri (Apple's voice recognition) or CarPlay won't work at all. I really dislike Siri and have it disabled on my phone.

I might give it another try if I can use Galileo or Garmin StreetPilot over CarPlay. About
